I used the method that STT posted above. Re-crimped the female inverted flare end to some -6an hose I had lying around.. Cost me a buck at the local hydraulic shop.



Another option that I stumbled upon uses an Earl's Saginaw type fitting for GM models. It adapts our M14x1.50 male inverted flare off the pump bracket directly to a male -6an fitting. It seems a few Stealth/3000GT guys use it in their setups.



The site I got the above method from has a few other useful conversions that also apply to our cars. Check it out:

About a third of the way down, there are a set of links to more options.
